[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The flowchart shown in the attached diagram is for illustrative purposes only and does not necessarily include all content and operations / steps, nor does it necessarily have to be performed in the order described. For example, some operations / steps can be broken down, combined, or partially merged, so the actual execution order may change depending on the actual situation.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a water heater provided in one embodiment of this application.

[0036] like Figure 1 As shown, the water heater 10 includes an inlet pipe 110, an outlet pipe 120, an intermediate pipe 130, an air supply pipe 140, a controller (not shown), a water flow sensor 101, a switch control valve 102, an ozone generator 103, a first water pump 104, a container 105, and a heating device 106.

[0037] For example, the intermediate pipe 130 connects the inlet pipe 110 and the outlet pipe 120. The outlet end of the outlet pipe 120 is equipped with a water point, such as a faucet, shower head, microbubble generator, etc. The user can obtain bathing water provided by the water heater 10 by turning on the water point.

[0038] The inflation pipe 140 is connected to the intermediate pipe 130. When the ozone generator 103 installed in the inflation pipe 140 is working, the ozone gas generated by the ozone generator 103 can be transported to the intermediate pipe 130 through the inflation pipe 140.

[0039] The switch control valve 102 is installed in the intermediate pipe 130. When the switch control valve 102 is closed, it can shut off the water in the intermediate pipe 130.

[0040] The first water pump 104 is installed in the water outlet pipe 120. The first water pump 104 can pressurize the water flowing through the water outlet pipe 120 and the water in the container 105, so as to cause the ozone gas generated by the ozone generator 103 to dissolve in the water and form a gas-liquid mixture with a high gas concentration.

[0041] A water flow sensor 101 is installed in the water inlet pipe 110 and is used to send a water flow signal to the controller when water flow is detected, so that the controller can control the switch of the control valve 102, the ozone generator 103 and the first water pump 104 according to the water flow signal.

[0042] An ozone generator 103 is installed in the inflation pipe 140 to generate and supply ozone gas to the inflation pipe 140.

[0043] The container 105 is installed in the water outlet pipe 120 and is used to contain the gas injected through the air filling pipe 140 and the water input through the water inlet pipe 110, so that the ozone gas generated by the ozone generator 103 and the water flowing into the container 105 through the intermediate pipe 130 can be mixed to form a gas-liquid mixture with a high gas concentration, which can be used as bathing water.

[0044] The water inlet of the heating device 106 is connected to the water inlet pipe 110, and the water outlet of the heating device 106 is connected to the intermediate pipe 130. It is used to heat the water flowing into the heating device 106 from the water inlet pipe 110, for example, based on the bathing temperature set by the user, to heat the water input into the water inlet pipe 110 to the preset water temperature, which is not limited here.

[0045] The controller (not shown) is connected to the on / off control valve 102, the ozone generator 103, and the first water pump 104, and is used to control the on / off of the on / off control valve 102, the ozone generator 103, and the first water pump 104. For example, the controller can control the on / off control valve 102, the ozone generator 103, and the first water pump 104 based on the water flow signal sent by the water flow sensor 101. For example, the controller is also connected to the water flow sensor 101 to receive the water flow signal sent by the water flow sensor 101; the controller is also connected to the heating device 106 to control the heating device 106 when the user needs hot water.

[0046] Please see Figure 2 , Figure 2 This is a schematic diagram of another water heater provided in one embodiment of this application.

[0047] In some embodiments, such as Figure 2 As shown, the inflation conduit 140 includes at least one inflation branch pipe for supplying ozone gas and / or a mixture of gases to the intermediate conduit 130.

[0048] For example, the inflation conduit 140 includes a first inflation branch 141 and / or a second inflation branch 142.

[0049] For example, the ozone generator 103 is disposed on the first gas filling branch pipe 141, and the ozone gas generated by the ozone generator 103 is delivered to the intermediate pipe 130 through the first gas filling branch pipe 141.

[0050] For example, the second inflation branch pipe 142 is connected to the outside and is used to supply air to the intermediate pipe 130. The air input through the second inflation branch pipe 142 can adjust the ozone concentration in the mixed gas input from the inflation pipe 140 to the intermediate pipe 130, thereby adjusting the ozone microbubble content in the microbubble bath water.

[0051] For example, the ozone generator 103 can also be installed on the second inflation branch pipe 142 that is connected to the outside, and the mixture of air gas and ozone gas can be directly input through the second inflation branch pipe 142. For example, the mixture of gas with a preset ozone concentration can be input through the second inflation branch pipe 142, which is not limited here.

[0052] In some embodiments, such as Figure 1 As shown, the inflation pipe 140 is equipped with a flow control valve 107. Specifically, at least one flow control valve is installed on at least one inflation branch pipe, such as... Figure 2 As shown, a first flow control valve 1071 is provided on the first inflation branch pipe 141, and a second flow control valve 1072 is provided on the second inflation branch pipe 142. The flow control valve 1071 can be, for example, a one-way valve. The flow control valve 1071 can control the flow direction of gas in the inflation pipe 140, prevent gas backflow in the inflation pipe 140, and improve inflation efficiency.

[0053] In some embodiments, such as Figure 1 As shown, the first water pump 104 is located at the outlet end of the container 105. When the first water pump 104 is started, it provides negative pressure to the container 105 to extract water from the container 105, thereby causing ozone gas to form a gas-liquid mixture with a high gas concentration in the water.

[0054] Please see Figure 3 , Figure 3 This is a schematic diagram of another water heater provided in one embodiment of this application.

[0055] In some embodiments, such as Figure 3 As shown, the first water pump 104 is located at the water inlet of the container 105. When the first water pump 104 is started, it provides positive pressure to the container 105 to pressurize the water in the container 105, so as to cause ozone gas to dissolve in the water and form a gas-liquid mixture with a high gas concentration.

[0056] By example, the pressurization effect of the first water pump 104 allows ozone gas and water to mix under higher pressure, thereby increasing the ozone gas content in the gas-liquid mixture and improving the user experience.

[0057] Please see Figure 4 , Figure 4This is a schematic diagram of another water heater provided in one embodiment of this application.

[0058] In some embodiments, such as Figure 4 As shown, the water heater 10 also includes a second water pump 108.

[0059] For example, the second water pump 108 is provided in the water inlet pipe 110 to pressurize the water input into the water inlet pipe 110, thereby increasing the water pressure during bathing and improving the user experience.

[0060] It is understood that the structures in the above embodiments can be combined with each other. Please refer to... Figures 5-8 , Figures 5-8 These are schematic diagrams of the water heater provided in the embodiments of this application.

[0061] like Figure 5 As shown, when the water heater 10 includes the second water pump 108, the first water pump 104 can also be installed at the water inlet of the receiving device 105 to provide positive pressure to the receiving device 105. Here, the positions of the first water pump 104 and the second water pump 108 are not limited.

[0062] like Figure 6 As shown, the water heater 10 may simultaneously include at least one gas-filling branch pipe (e.g., a first gas-filling branch pipe 141 and a second gas-filling branch pipe 142) and a second water pump 108. Ozone gas generated by the ozone generator 103 is input through the first gas-filling branch pipe 141, and air is input through the second gas-filling branch pipe 142 to adjust the ozone concentration in the mixed gas in the intermediate pipe 130, thereby improving the flexibility of the water heater; at the same time, the second water pump 108 increases the water pressure in the inlet pipe 110, thereby improving the user's water usage experience.

[0063] like Figure 7 As shown, when the water heater 10 includes at least one gas-filling branch pipe (e.g., the first gas-filling branch pipe 141 and the second gas-filling branch pipe 142), the first water pump 104 can also be installed at the water inlet of the container 105 to provide positive pressure to the container 105, causing the ozone gas generated by the ozone generator 103 to dissolve in the water and form a gas-liquid mixture with a high gas concentration.

[0064] like Figure 8 As shown, when the water heater 10 includes at least one air supply branch pipe (e.g., the first air supply branch pipe 141 and the second air supply branch pipe 142) and the second water pump 108, the first water pump 104 can also be installed at the water inlet of the container 105 to provide positive pressure to the container 105, causing the ozone gas generated by the ozone generator 103 to dissolve in the water and form a gas-liquid mixture with a high gas concentration.

[0065] Please see Figure 9 , Figure 9 This is a schematic flowchart illustrating the steps of a water heater control method provided in an embodiment of this application.

[0066] like Figure 9 As shown, the water heater control method includes steps S100-S300.

[0067] Step S100: Obtain the first water flow signal sent by the water flow sensor 101.

[0068] For example, when a user turns on the water outlet, water enters the water heater 10 through the inlet pipe 110. The water flow sensor 101 detects the water flow in the inlet pipe 110 and sends a first water flow signal to the controller.

[0069] Step S200: Based on the first water flow signal, start the first water pump 104 and ozone generator 103, and close the switch control valve 102 to inflate the container 105.

[0070] For example, the controller is connected to the switch control valve 102, the ozone generator 103, the first water pump 104, and the water flow sensor 101. When the controller receives the first water flow signal sent by the water flow sensor 101, it will start the first water pump 104 and the ozone generator 103 based on the first water flow signal, close the switch control valve 102, cut off the input water in the intermediate pipe 130, and start the first water pump 104 and the ozone generator 103 to generate ozone gas. The ozone generator 103 will also increase the pressure in the outlet pipe 120 and the container 105 through the first water pump 104, so that a large amount of ozone gas will enter the outlet pipe 120 and the container 105 on the outlet pipe 120 to inflate the container 105.

[0071] Step S300: When the containing device 105 is inflated to meet the first preset condition, the first water pump 104 and the ozone generator 103 are turned off, and the switch control valve 102 is opened so that water can be discharged through the water outlet pipe 120.

[0072] For example, when the inflating device 105 meets the first preset condition, the inflating of the inflating device 105 is stopped, the controller controls the first water pump 104 and the ozone generator 103 to shut down, and opens the switch control valve 102, so that the water in the intermediate pipe 130 can enter the outlet pipe 120 and the inflating device 105, where it mixes with the ozone gas in the inflating device 105 to form a gas-liquid mixture containing ozone, and provides the user with bathing water containing ozone through the outlet pipe 120.

[0073] In some embodiments, inflating the containing device 105 to meet a first preset condition includes at least one of the following: inflating the containing device 105 for an inflation time of a first preset duration; or a liquid level sensor in the containing device 105 detecting that the current liquid level is within a preset range.

[0074] For example, the first preset duration can be set according to actual needs. For instance, the first preset duration can be set to 5 seconds. After the container 105 is inflated for 5 seconds, the first water pump 104 and the ozone generator 103 are turned off, and the switch control valve 102 is opened so that the gas-liquid mixture containing ozone can be output through the water outlet pipe 120.

[0075] For example, since the ozone generated by the ozone generator 103 is filled into the container 105, it creates pressure on the liquid in the container 105. As the amount of gas filled into the container 105 increases, the pressure in the container 105 increases and the liquid level drops. When the liquid level sensor in the container 105 detects that the current liquid level is within a preset range, for example, when the current liquid level is lower than the preset liquid level, the first water pump 104 and the ozone generator 103 are turned off, and the switch control valve 102 is opened so that the gas-liquid mixture containing ozone can be output through the water outlet pipe 120.

[0076] Please see Figure 10 , Figure 10 This is a schematic flowchart illustrating the steps of another water heater control method provided in an embodiment of this application. Figure 10 As shown, in some embodiments, the control method of the water heater further includes: step S400, when the water outlet through the water outlet pipe 120 meets the second preset condition, closing the switch control valve 102, and restarting the first water pump 104 and the ozone generator 103 to charge the containing device 105.

[0077] For example, during the water dispensing process of the water heater 10, the ozone gas generated in step S200 forms microbubbles and is discharged from the water heater 10 along with the bathing water. After a period of water dispensing, the amount of ozone gas generated in step S200 decreases, and the containing device 105 needs to be refilled with gas. Specifically, when the water dispensing through the outlet pipe 120 meets the second preset condition, the switch control valve 102 is closed, and the first water pump 104 and the ozone generator 103 are restarted to refill the containing device 105 with gas.

[0078] In some embodiments, the water discharge through the water outlet pipe 120 to meet the second preset condition includes at least one of the following: the water discharge through the water outlet pipe 120 for a duration of the second preset duration; and the water discharge volume through the water outlet pipe 120 reaching a preset water discharge volume.

[0079] For example, the second preset duration and preset water output can be set according to actual needs. For instance, when the ozone gas in the container 105 is exhausted, the water output duration reaches the second preset duration and / or the water output reaches the preset water output, and the container 105 needs to be refilled. Of course, it is not limited to this and is not limited here.

[0080] In some embodiments, starting the first water pump 104 includes: sending a speed command to the first water pump 104 to control the speed of the first water pump 104, and adjusting the speed of the first water pump 104 to adjust the air intake and water intake of the receiving device 105.

[0081] For example, the controller can adjust the rotation speed of the first water pump 104 via a rotation speed command to regulate the air intake and water intake of the container 105. For instance, during the process of the liquid level rising in the container 105, the rotation speed of the first water pump 104 can be gradually increased via a rotation speed command to adapt the rotation speed of the first water pump 104 to the actual needs, which will not be elaborated here.

[0082] Please see Figure 11 , Figure 11 This is a schematic flowchart illustrating the steps of another water heater control method provided in an embodiment of this application. Figure 11 As shown, in some embodiments, after the switch control valve 102 is opened and water is discharged through the outlet pipe 120, the control method of the water heater further includes: step S500, acquiring the second water flow signal sent by the water flow sensor 101, and starting the heating device 106 to heat the water input into the inlet pipe 110.

[0083] For example, when a user needs hot water, the water heater 10 can heat the water entering through the inlet pipe 110 via the heating device 106. Specifically, after the housing 105 is inflated and the switch control valve 102 is opened, water in the intermediate pipe 130 flows to the outlet pipe 120, while water simultaneously enters the inlet pipe 110. The water flow sensor 101 will detect a water flow signal in the inlet pipe 110 again. At this time, the water flow sensor 101 sends a second water flow signal to the controller. Based on this second water flow signal, the controller activates the heating device 106 to heat the water.

[0084] Please see Figure 12 , Figure 12 This is a schematic flowchart illustrating the steps of another water heater control method provided in an embodiment of this application. Figure 12 As shown, in some embodiments, the control method of the water heater further includes: step S600, when the housing 105 is inflated to the first preset condition, the second water pump 108 is started to pressurize the water input into the water inlet pipe 110.

[0085] For example, when the housing 105 is inflated to the first preset condition, and the controller controls the water heater 10 to stop inflating and start discharging water, the second water pump 108 installed in the water inlet pipe 110 is started. The second water pump 108 pressurizes the water entering the water heater 10, increases the water pressure when using water, and improves the user experience.
